End users want lots of TV channels, the big content networks are providing. Everything (including DNS) is done over HTTPS today, which is very NAT friendly. CGN in the eyeball ISP world can easily achieve 10:1 or 50:1 IPv4 oversubscription, and with that, we have enough IPv4 for ever... Until the police declares that 1000:1 oversubscription (combine with encryption everywhere) makes their job impossible and enforce some limitation. Well, yes, end-to-end communication will be lost forever. But since the "EVERYONE MUST HAVE A FIREWALL!" crowd broke that for the normal household anyway, it's lost anyway. And, the above (combined with uneducated ISP blocking IPv6 extension headers) is even more frightening.... it forces the Internet in the hands of a couple of cloud providers and is a real ossification of the Internet ----%<--------%<----------- Now, I do not have any solution -éric
